LIQUID-FUEL BURNER.

Specification of Letters Patent.

Patented Sept. 12, 1905.

Application filed March 4, 1904. Serial No. 196,534.

To 111/ whom it may concern.-

Be it known that I. THOMAS J. COLBERT, a citizen of the United States, residing at Silver Lake, in the county of Kosciusko and State oflndiana, have invented certain new and useful Improvements in Liquid-Fuel Burners; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

My present invention relates to improvements in liquid-fuel burners, or that class sition of the parts, of being connected to most all kinds of heating devices, such as stoves or furnaces, for burning crude oils therein or, if so desired, to be employed in cookingstoves, although more particularly designed and intended for burning crude oil or petroleum in heatingstoves, in which instance it has herein been illustrated and described.

Among some of the objects and advantages of my invention may be mentioned the saving in cost of fuel, cleanliness, convenience, ease and readiness of attachment, quickness and cheapness of repairing, inexpensive cost of manufacture, and the providing of means for always keepingcool that portion of the oil-supply or feed pipe which rests in the stove, thus preventing the discharge end of said pipe, directly over the flame, from becoming so heated that the oil will try and thickentherein instead of flowing therefrom, as is the objection to most devices of this nature, also in removing all danger by creating a proper combustion.

My invention consists,essentially, referring in general terms to the construction of my liquid-fuel burner attachment, of asuitablyarranged source of supply, a feed or supply pipe, means for feeding or distributing the liquid to the flames, and means for keeping the discharge end cool, so as to permit of the free and uninterrupted discharge or flow of the oil to the flame, and the peculiar and novel construction, arrangement, and combination of the several parts, as will be specifically referred to in detail hereinafter and set forth in the subjoined claims in accordance with the statutes in such cases made and provided therefor.

Referring to the annexed drawings, illustrating my invention, and wherein the same letters of reference indicate like parts wherever occurring throughout the several views, Figure 1 is a general view, in side elevation, partially broken away, so as to illustrate the application of my invention in connection with a heating-stove. Fig. 2 isa vertical longitudinal sectional view in detail through the cold-air chamber. Fig. 3 is a detail view, in side elevation, partially in section and broken away, of the discharge end of the feed or oilsupply pipe and the sprayer connected thereto; and Fig. 4: is a plan view of the sprayer looking at the bottom.

In describing my said invention and referring in detail to the difl'erent parts 01' mechanical features thereof, as illustrated throughout the various views of the annexed drawings and indicated by means of the letters of reference as a foresaid, A refers to the heatingdcvice, which in this instance is shown to be a heating-stove of ordinary construction, in the bottom of which is placed a bed of brick-bats or similar suitable absorbent heat and flame retaining material, as shown at 1;.

Inside the stove and extending upward for a suflicient distance above the bed of heat-retaining material, so as to escape the direct action of the flame, and passing out through an opening in top of stove, so as to extend a short distance above same, is the cold air chamber B, which is lirmly supported from top of stove by flange Z), riveted or bolted thereto or otherwisesuitablysupported. Cold-airchamber B, as shown, is a hollow body in the form of a sleeve, open at both ends and provided around its top with an enlarged annular chamber having a series of perforations or small openings 0. Through said openings and the open top of said chamber, as indicated byarrows in Fig. 1, currents of cold air will constantly pass down said chamber suflicient to always offset the direct action of the heat from the flames upon the discharge end (Z of feedpipe D and sprayer (2, thus keeping these members cool enough to prevent the oil from thickening or drying therein and permitting the oil to flow from the discharge end of said pipe down over the sprayer e and be properly distributed to the flame.

Feed or supply pipe D is connected to a suitably located and supported tank or reser voir F (not necessary to be here shown in detail) of any preferred style or construction, provided with a securely-closed mouth or receiving-opening and a vent for holding the IIO supply of liquid fuel, which I intend and prefer should be crude oil. Said feed-pipe, the lower portion of which extends loosely and freely down in the cold-air chamber, may be supported from the ceiling by a wire, if necessary, as shown at g, and is also provided with any ordinary style of valve it for regulating the flow of oil as it passes out from the tank down said feed or supply pipe and out of the discharge end or mouth (Z onto the sprayer e. Said sprayer is located a short distance above and within the bottom of the cold-air chamber and being in form somewhat like an inverted funnel, but closed at its top, so that said oil will flow down the grooves or flutes e and the outside of the sprayer, which is large enough in circumference at the base (see more particularly Figs. 3 and 4:) so that said oil will be dropped or sprayed on the flames, (see Fig. 1,) and as it burns up all waste products or smoke, if any, which may arise will pass off up the Stovepipe I in the usual manner.

As is more clearly and elaborately shown in detail in Fig. 3, sprayer e is preferably connected to discharge end (Z of the feed-pipe by wire arms k, which are intended to be sufliciently resilient to be readily sprung into small openings in said feed-pipe adapted to receive them, so said sprayer may be quickly detached from said pipe, if desired.

It will of course be understood that while I have herein shown and described a preferred form of construction of the several parts constituting my invention slight changes and variations in the style, form, and arrangement of these parts as may from time to time be suggested and be found necessary according to the style of heating device to which they are to be' attached may be made so long as within the scope and spirit of and confined to the principles of the invention.

I am aware of a few devices somewhat similar to mine; but these have not the practical advantages of mine. However, I do not, therefore,claim my construction broadly; but

What I claim is 1. The combination with a stove having an opening in its top, of a vertical sleeve received and removably secured in the opening and depending within the stove, the lower end of the sleeve being open, the upper portion of the sleeve extending above the top of the stove and provided with an enlargement having openings therein, a feed-pipe of less diameter than the sleeve and depending to a point within and near the lower end of the sleeve, the lower end of the feed-pipe being open and a sprayer removably supported beneath the open end of the feed-pipe and within the sleeve.

2. The combination with a stove having an opening in its top, of an open-ended sleeve received within the opening and extending above and below the top of the stove, an apertured enlargement at the upper end of the sleeve, a feed-pipe of less diameter than the sleeve and received therein, and a sprayer located at the lower open end of the feed-pipe.

3. A stove comprising a body portion, an open-ended vertical sleeve projecting into the stove, an apertured-enlargement carried by the exposed portion of the sleeve, a feed-pipe of less diameter than the sleeve and receivable therein through its outer end, air being admitted through the upper open end of the sleeve and through the apertures, and a sprayer located beneath the lower open end of the feed-pipe.

4. The combination with a stove, of a vertical open-ended sleeve extending into the stove, the upper end of the sleeve extending above the stove, an apertured enlargement carried on the upper end of the sleeve, a feed- I pipe of less diameter than the sleeve and received therein through its upper open end, a bed of refractory material located within the stove and beneath the lower open ends of the sleeve and feed-pipe, air being admitted through the apertures in the enlargement and through the annular space between the periphery of the feed-pipe and the inner periphery of the sleeve.

5. The combination with a stove, of a ver-' tically-located open-ended sleeve projecting into the stove and extending some distance thereabove, an enlarged apertured chamber located on the upper exposed portion of the sleeve, and a liquid-fuel-feed pipe projecting into the sleeve from its upper open end and discharging into the stove.

In testimony whereof I have aflixed my signature in presence of two witnesses.
